I installed a 3rd party download manager (can't remember the name) and now each of my three browsers:
Safari
Chrome
Firefox

Won't download files, the browser simply points to a URL instead of initiating the download. I have tried re-setting each and nothing appears to be working.
Has anyone any ideas? Or experienced this problem?

cheers guys, I have uninstalled the dl manager with appcleaner, I think it may have left a preference file behind.
I only thought I'd give the manager a try but this has left a sour taste in my mouth tbh...
